This study about the absorption of iron and magnesium as metal ions in water solutions and kaolin were used as adsorbents. The power of Kaolin as adsorbent still very low so it is necessary to modify kaolin using acyl sulfonate (ABS) surfactant which is an organic compound. The aim is to increase the absorption capacity of kaolin in absorbing metal ions contained in water using modified kaolin to get effective absorption results in absorbing metal ions, especially iron, this research was carried out by varying microwave irradiation time 5, 15, 30, 50 and 80 minutes using surfactant kaolin modification and without surfactant modification, the waste used was artificial waste with an initial concentration of 100 mg / l. The samples were analyzed using Atomic Absorption Spectrophotometers (AAS), while the characteristics used were Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM). Kaolin modification with microwave use in the adsorption process results in a decrease in artificial Fe waste at 3 minutes irradiation time on modification of efficiency reduction of 72% and Mg waste at 30 minutes decreased by 61%.
